Estimating the term…
Disclosed are combinations of amino phenols, wherein said phenols contain a substantially saturated hydrocarbon substituent of at least 10 aliphatic carbon atoms, and one or more detergent/dispersants selected from the group consisting of (I) neutral or basic metal salts of an organic sulfur acid, phenol or carboxylic acid; (II) hydrocarbylsubstituted amines wherein the hydrocarbyl substituent is substantially aliphatic and contains at least 12 carbon atoms; (III) acylated nitrogen-containing compounds having a substituent of at least 10 aliphatic carbon atoms; and (IV) nitrogen-containing condensates of a phenol, aldehyde and amino compound. Fuels and lubricants containing such combinations as additives are particularly useful in two-cycle (two-stroke) engines.
A lubricant composition for two-cycle engines comprising a major amount by weight of at least one oil of lubricating viscosity and a nitrogen-containing organic composition comprising a combination of:
A lubricant composition for two-cycle engines comprising a major amount by weight of at least one oil of lubricating viscosity and a nitrogen-containing organic composition comprising a combination of:
A lubricant composition for two-cycle engines comprising a major amount by weight of at least one oil of lubricating viscosity and a nitrogen-containing organic composition comprising a combination of:
A composition as claimed in claim 35 wherein the amino compound is of the formula ##STR35## wherein U is an alkylene group of 2 to 10 carbon atoms;
